BED-PLATE FOR PAPER AND RAG ENGINES- SPECIFICATION f rm ng p r of L r Pe N 771,582, dated October 4, 1904.

Application filed April 24, 1903.

To all whom it may concern.-

Be it known that I, HERBERT R. SIMoNDs, a citizen of the United States,residing at Dayton, in the county of Montgomery and State of Ohio, haveinvented certain new and useful Improvements in Bed-Plates for Paper andRag Engines; and I do hereby declare the following to be a full, clear,and exact description of theinvention, such as will enable othersskilled in the art to which it appertains to make and use the same. v V

My invention relates to that class of bedplates in which the blades areso arranged as to form several series of diamond shaped knives; and ithas for its special object to provide means whereby this result may beobtained without the use of the old dovetailing feature, which inpractice has been found to weaken the blades.

. My invention consists in the novel construction fully andclearlycdescribed and illustrated in the accompanying specification anddrawings.

In the drawings, Figure 1 is a top plan view of my improved bed-plate.Fig. 2 is a perspective view of one of the blades employed in my device.

' A in the drawings represents a frame of suitable shape, size, andmaterial adapted to inclose a series of blades B, bent into a zigzagform and so arranged that the external angles of adjacent blades are incontact with each other, thus forming a series of diamondshaped recessesbetween each pair of blades, the construction of the blades being suchthat a perpendicular line we dropped from one of the sides of the framewill pass through but one of the points of contact of the blades.

Serial No. 154,173. (No model.)

C C are blocks, preferably of wood, adapted to fit into saiddiamond-shaped recesses and also in the recesses formed betweentheblades and said frame A to prevent all chance of the blades slipping. DD D are bolts provided with nuts D D, passing through said frame,blades, and blocks and adapted to hold the same rigidly together. In thedrawings the apexes of the exterior angles of the blades have beenillustrated as being pointed; but, if desirable, they may be flattenedto insure greater rigidity. Hence it is evident that this constructionwill have all the qualities of the old dovetailed plate with theadvantage of being much stronger and durable.

What I claim, and desire to secure by Letters Patent, is-

The herein-described diamond bed-plate for paper and rag engines,comprising among its members, a plurality of separate blades bent intoZigzag form and arranged with the external angles of adjacent plates incontact with each other, whereby two series of substantially continuousparallel cutting edges are provided, the cutting edges of one seriescrossing those of the other series angularly, the construction of saidblades being such that not more than one of the points of contact of theplates will be in a perpendicular line dropped from one side of theframe, substantially as described.

In testimony whereof I afiix my signature in the presence of twowitnesses.

HERBERT R. SIMONDS.
